Method, terminal and device arragement for transferring a message to a terminal

ABSTRACT

The invention relates to a method, device arrangement and a terminal for transferring a message received in a first terminal in a controlled manner from said first terminal to a second terminal. In the method, the messages are searched for possible references to resources outside the message, and information is downloaded from these resources for later examination.

FIELD OF THE INVENTION

The invention relates to a method for transferring a received messagefrom a first terminal to a second terminal. The invention also relatesto a system and terminals for transferring a received message from afirst terminal to a second terminal. In particular, the inventionrelates to a system for transferring a received message to a mobileterminal and a mobile terminal that receives the message.

BACKGROUND OF THE INVENTION

The use of e-mail has become an everyday habit, and the majority ofpeople use e-mail both at work and during leisure time. In principle,the only requirements for using e-mail are a terminal with e-mailcapability and a connection to an e-mail server. The conventional way ofusing e-mail is to use it at a personal computer, but nowadays there isa wide variety of mobile terminals, such as portable computers, handheldcomputers, such as Palm, PocketPC etc., and mobile stations, such ascommunicator-type devices with Internet capabilities.

If a mobile terminal provides a possibility to connect to the Internetusing a GPRS connection or a WLAN connection, for example, it isgenerally also possible to use and read e-mail with it. However, thesituation is not always this, and a device such as a portable computeror other terminal can be for various reasons unavailable for an Internetconnection for part of the time or always. Then the terminal is in aso-called offline state, i.e. it does not have a connection to anexternal information net-work. In cases like this, such as when leavingone's workstation at the place of work, it may be possible to downloadthe arrived e-mail messages from the personal computer to this portableterminal for later viewing. Such systems are well known in the art. Forexample the patent application US2002/0120696 discloses a method forsynchronizing user-selected files, folders and folder hierarchiesbetween a host system and a mobile data communication device.

However, the e-mail messages may have various links to addresses outsidethe actual message. Links like this include the URL or web addresses,which can be embedded in the text of the e-mail message as hyperlinks.These links may, for example, provide further information on the subjectmatter of the e-mail message, or the sender of the e-mail just wanted toinform the recipient of an interesting web page. However, when thee-mail messages have been downloaded to a terminal which is offline forreading them later, it is not possible to access the web addresses inthe messages, because the terminal does not have a network connection.

In addition to e-mail, other types of messages can also containreferences to sources outside the message. For example, in the MMS(Multimedia Messaging Service) messages used in mobile stations it ispossible to send text, image and sound. MMS is an open industrialstandard, and MMS messages can be transferred in the currently existingdata networks and protocols. The MMS message itself is independent ofthe method of transmitting information, and the possibilities for usingit are not limited to the most commonly used cellular networks, such asthe GSM or WCDMA networks. An example of other types of messages is apush message, which is transmitted to a mobile terminal.

A Japanese patent document JP2002183059 A discloses a system wherein auser terminal, which can not connect to a web server, creates an e-mailcontaining a request to obtain information from the web server, andsends the e-mail to a proxy server. The proxy server analyzes therequest written in the e-mail, connects to the requested web server andcollects information from the web server. Then the proxy server packsthe information into a file, attaches it to replying e-mail and sendsthe replying e-mail to the user terminal. Finally, the user terminalextracts the web information from the attached file of the replyinge-mail and stores it into storage. In this solution the user specifiesthe URL's he wants to connect and the messages are sent in bothdirections between the user terminal and the proxy server.

It is an object of the invention to present a method for downloading thewww-pages or other external resources shown by the hyperlinks in thereceived message for later examination or use.

SUMMARY OF THE INVENTION

The objectives of the invention are achieved by a method and a system inwhich the received user's messages are searched for links to resourcesoutside the message, and information is downloaded from these resourcesfor later examination. The method, device arrangement and terminalsaccording to the invention are characterized in what is set forth in theindependent claims. Some preferred embodiments of the invention aredescribed in the dependent claims.

The basic idea of the invention is the following: The content of themessages arriving at the first terminal is observed, and possible linksto resources outside the message, such as URL addresses pointing towww-pages, are searched for from the messages. If such a reference orlink is found from the message, the resource shown by the link isvisited or its content is analysed. The resource shown by the link, suchas a web page or a multimedia file, for example, can be downloaded to acomputer into a cache, possibly reprocessed and transferred to a secondterminal, such as a mobile terminal, in a controlled manner usually atthe same time as the actual messages are downloaded or transmitted toit. The resource or information based on said resource may also betransferred at different time as the actual message or it may not betransferred at all, depending on the type of said information.

The invention provides the advantage that the outside resource to whichreference was made in the sender's message is immediately available,even if the terminal does not have a connection to an externalinformation network.

In addition, the invention provides the advantage that the need toconnect to an external information network with a mobile terminal isreduced, and economic savings, for example, can thus be achieved.

Furthermore, the invention provides the advantage that by analysing thelink in the message in advance it is possible to avoid a visit to aresource which is unnecessary or unwanted for the user, such aswww-pages sent for advertising purposes.

Yet another advantage of the invention is saving the limited memorycapacity of the mobile terminal by controlling the informationtransferred to it.

One aspect of the invention provides a method for transferring a messagereceived in a first terminal in a controlled manner from said firstterminal to a second terminal. In this method the message is searchedfor references to resources outside the message, and information isdownloaded from these resources for later examination or use andoptional transfer to said second device. Said information, parts of itor modified information may or may not be transferred to the seconddevice. The decision of whether or not to transfer said information, andhow to possibly modify it, to the second terminal may be done accordingto predefined rules or by other criteria in any of the terminals.

Another aspect of the invention provides a device arrangement fortransferring a message received in a first terminal in a controlledmanner from said first terminal to a second terminal by the method ofthe invention. The device arrangement comprises a first terminal, asecond terminal and means for transferring information from the firstterminal to a second terminal. The device arrangement also comprisesmeans for searching the messages for references to resources outside themessage, for downloading information from these resources for laterexamination and for optional transfer of said information to said secondterminal.

Another aspect of the invention provides a first terminal comprisingmeans for receiving a message and means for transferring said message ina controlled manner from said first terminal to a second terminal by themethod of the invention. The terminal also comprises means for searchingsaid message for references to resources outside the message, fordownloading information from these resources for later examination andfor optional transfer of said information to said second terminal.

Another aspect of the invention provides a second terminal, such as amobile terminal, comprising means for receiving a message. Said terminalalso comprises means for searching said received message for referencesto resources outside the messages by the method of the invention, foranalysing the information in said referenced resources outside themessage and for transferring said information to said terminal, and formaking a decision on the processing of this information.

DEFINITIONS

In this connection, the term “computer” means generally the first devicefrom which e-mail is transferred to the mobile (second) terminal withthe method according to the invention. The computer can be e.g. apersonal computer of the PC or Macintosh type, and it has a capabilityto establish a connection to an external information network, such asthe Internet. In general, such a computer is an immobile computer, suchas a desktop PC or a Macintosh, but it can also be a portable computeror other terminal which is capable of handling e-mail and from which thee-mail can be transferred to a mobile terminal defined later with amethod according to the invention. The “computer” can also be a similarmobile terminal as defined later. A “computer” can also be a server inan information network or a server that transmits or mediates multimediamessages, for example. The essential characteristic of the methodaccording to the invention is the ability to transfer messages from acomputer to another terminal using any suitable connection.

The term “terminal” used in this connection means any device that iscapable of processing electronic information and is suitable for use inthe method and device arrangement according to the invention. Theterminal can be, for example, a computer, a PDA (Personal DigitalAssistant) or a mobile phone of a cellular network. The terminal can bemobile or stationary. The terminal can also be a server, such as ane-mail server or a server of a cellular communication network, such as aserver that transmits or mediates messages.

The term “mobile terminal” used in this connection means any terminalwhich can be moved and which can receive a message. With regard toe-mail, it is possible to use an e-mail application or read e-mail withthe terminal, or e-mail can be transferred to it from the first device.Other types of messages that can be received by the terminal include anMMS message or a push message. Examples of such terminals are a portablecomputer or a PDA (Personal Digital Assistant), i.e. a handheldcomputer, which are based on the PalmOS, PocketPC, Windows CE, Symbian,BeOS or Linux operating systems, for example. Examples of devices likethis include Nokia Communicator, Palm, Handspring and HandEra. Inaddition, many modern mobile phones include some features of a handheldcomputer, such as e-mail capability, in which case they are also coveredby the definition. The terminal can also provide a possibility toestablish a connection to an external information network, but it is notnecessary. The terminal can also have characteristics of a mobile phoneoperating in a cellular network. With regard to the invention, it isessential that the terminal can be connected to the first device, fromwhich information can be downloaded or transmitted to it, such as theuser's e-mail or at least part thereof, or a multimedia message or apush message. This connection can be radio frequency, infrared or wiredconnection or any other suitable connection.

The term “transfer” in connection with the transfer of e-mail or othermessages and the referred resources means an event in which information,such as e-mail or parts thereof is transferred or copied from an e-mailprogram or system or an associated cache memory of the first device to asecond device, preferably the mobile terminal defined above. Copies ofthe e-mail messages can remain in the first device, or they can beremoved from it in connection with the transfer event. A transfer eventlike this is generally also called synchronization, meaning that afterthe transfer the first and the second device will have similar oressentially similar files or e-mail messages and the informationpossibly referred by the message. However, when the method according tothe invention is used, the messages will probably not be exactly similarin both devices, because the method can reduce or increase the amountand/or size of the information transferred to the second device. Methodsand programs for transferring information from the first device to thesecond device are well known. For example, the PC Suite program of Nokiacan be used for transferring information between a PC and a Nokia mobilephone. Any suitable program or a set of programs can be used fortransferring information from the first device to the second device,depending on the equipment used. In connection with a multimedia messageor a push message, “transfer” means an event in which information, suchas a message, is transferred from the first, transmitting terminal to asecond, receiving terminal. The information to be transferred can beinformation, which is modified from the original information at theexternal resource. The information to be transferred can also beinformation concerning the information in the external resource, such asinformation about its size and type. Information like this is necessaryfor estimating if the information in the external resource is suitablefor transferring to the second terminal. In this connection, the term“external resource” means any resource that is outside the actualmessage, but to which reference is made in the message or itsattachment. The reference may be in the form of a link, such as ahyperlink, and it can point to a web page, a news server, a file in theInternet or an intranet, such as a multimedia file, network disk, suchas a shared disk of a company's information system or other resource ora streaming-type data flow, for example. The link can thus be e.g. anURL address, which refers to an address according to the http, https orftp protocol, or an UNC path to a network resource. The link can referto a web page, but it can also refer to a mere file which can be locatedin an address according to the http, https, ftp or other suitableprotocol. The file can be an image file, sound file, video file, textfile, pdf file, compressed file, program file or any other file. Thelink can also refer to a data flow or a generable page or pages, such asa service or page implemented with the php language or like. Theprotocol used can also be any other suitable protocol, such as someother protocol used in the Internet or in a local area network.

The term “message” used herein means any message sent by sender, such ase-mail, multimedia message, push message or any other suitable message.Preferably the message is received by the first terminal.

The term “e-mail” means any e-mail according to any known e-mail system.The e-mail server can operate in any known operating environment, and itcan use any known protocol. The user can have a client program that issuitable for using and reading e-mail, or the e-mail can be read bymeans of a browser-based user interface, for example. Examples of knowne-mail client programs are, but are not limited to: Outlook, OutlookExpress, Eudora, Netscape Mail, Pegasus Mail, Lotus and Teamware Mail.

The term “multimedia message” means any type of message that supportsmultiple content, used in a cellular network system. An example of amultimedia message is the MMS message. Although the most common way totransfer a multimedia message is to transmit it from the first terminalto the second terminal, the actual message can also be transferred byusing other methods.

The term “push message” means any message used in the cellular networksystem, in which selected information is automatically transferred tothe user. The push technique is used e.g. in services in which theoperator transmits news or other selected information, such as sportsresults, to the client's mobile phone.

The term “compressing” means any known method for compressinginformation, in which the purpose of the method is to reduce theoriginal size of the information. The compression can be lossless orlossy. In lossless compression, all the original information isretained, although the information is compressed into a smaller size.Some examples of known lossless compression methods are the zip, rar andIhz methods. The gif or png types used in image files, for example, arepacked in a lossless manner, such as the gif image with the Ihzalgorithm. In lossy compression, some information is lost from theoriginal. When lossy compression is used, it is generally attempted tocarry it out in such a way that the lost pieces of information would besuch that they are not easily detected among the other information,whereby the quality of the original information would not suffer verymuch. Lossy compression methods are generally used in multimedia files,such as image, sound and video files, in which it is usually possible toselect the compression rate. This means compromising between the size ofthe file and the quality of information. Various compression methods andalgorithms are generally known in the art.

DETAILED DESCRIPTION OF THE INVENTION

In the method according to the invention, the incoming messages to thefirst device are monitored automatically and references to outsideresources are searched for from them. The system that monitors themessages can be, for example, built in the e-mail client program or itcan be a separate program or a plugin. It can also operate in an e-mailor other server, for example, or in a mobile terminal according to oneembodiment. The system that monitors the messages may operate in thefirst device, such as a computer, to which the e-mail messages aregenerally downloaded in normal use. The system that monitors themessages can also operate in some other device, such as a terminaltransmitting a multimedia message, a network transmitting a message, aserver operating in it or some other terminal. The method used by thissystem is characterized in that the reference in the message, preferablya hyperlink, is recognized from the actual received message, generallytext, and it is analysed or the address shown by it is visited. Theexternal resource to which reference was made in the message may bedownloaded to the cache of the first device, from which it can beprocessed further. In a case in which the reference in the messagerefers to an address which is defined as to be ignored, such as certainaddresses known from advertising purposes, it is not necessary todownload the external resource to the cache or even visit the address.

Because the referenced outside resource is meant to be possiblytransferred or copied later to a mobile terminal, which may have alimited memory or saving capacity, it is necessary to analyse theproperties of the external resource or file it refers, such as its size.It may be impossible to make a large file or a set of www-pages to fitin the memory of the terminal, or it would take space from otherinformation. In that case, it may be necessary to remove some extraelements, such as images of the www-pages, or advertising banners. Thecontent and size of the images can be analysed, and they can be e.g.reduced or recompressed using a larger compression rate, whereby theytake less space or fit better on the display of a small-sized terminal,for example. In addition, reducing the number of colours in the imagesor multimedia can reduce the file size.

Furthermore, various rules can be applied in connection with theanalysis of the outside resources, such as ignoring the elements incertain addresses. This may be necessary to avoid material sent foradvertising purposes, for example. Likewise, messages coming fromcertain addresses can be totally ignored. The recognition of elements ofa certain shape and/or located in a certain place can help to reduceso-called advertising banners, for example. The rules for handlingoutside resources can be preferably defined individually, taking intoaccount matters like the properties of the mobile device, such as memorycapacity, display resolution or sound properties, or taking into accountthe user's own preferences and definitions of acceptable and notacceptable web addresses, for example. The arrangement according to theinvention can handle outside resources fully automatically or it can,for example, check the user's approval for a certain procedure to becarried out, such as whether a certain image or web page may betransferred to the mobile device for later viewing.

It is possible to specify limit values for the information in theexternal resource concerning the size, type and quality, and when thesevalues are exceeded, the information is processed again, i.e. a decisionis taken on whether to transfer information to the second device assuch, as modified or not transferred at all. Size means the size of theinformation or the file in bytes, the type means the file type, such aswhether it is an image, sound, video, text, program or some other file.Quality can mean the relative quality of the information saved in thefile, like the resolution, compression rate or number of colours of animage or video file. The limit values specified for these meanpredetermined values that are compared to the current piece ofinformation; on the basis of this a decision is taken on reprocessingthe information.

According to one embodiment, size limits can be set to the images andother files, in which case e.g. images or files that exceed a certainlimit are not downloaded, or images, sound files or multimedia filesthat exceed a certain limit are recompressed to achieve a smaller filesize. Types of image files that are generally used include, for example,the bitmap types JPEG (JPG), GIF, BMP, PNG, WBMP, or TIFF, but any othertype of image, such as image types containing bitmap or vector graphics,or subtypes of these, can be applied. For example, the compression rateof an image of the JPG type is lossy, and it can be adjustedprogrammatically, leaving out small details and thus achieving a smallerfile size. According to a preferred embodiment, the image can be savedas a different type of image, thus achieving a smaller file size. Forexample, BMP or TIFF files can be large, because lossy compression isnot used in them. However, these image types can be recompressed using alossy method, such as JPEG, whereby a substantially smaller file size isobtained, with some compromise in quality. In many cases this does notcause much inconvenience, because a mobile terminal may be equipped witha small display on which the deterioration in the image quality is notdistinguished. When the file type is changed in connection withreprocessing, the reference to the file in the mobile message must alsobe changed to correspond to this new file type. The image resolution inpixels can also be reduced, the result being a smaller file and asmaller image size, which can fit on the small display of the terminalbetter. The number of colours contained by the images can also bereduced in order to reduce the file size. Methods for the abovementioned various reprocessing of images are well known.

Similar recompressing and resolution changing methods can also beapplied e.g. to multimedia files, such as sound or video files. Forexample, a sound file can be a compressed sound file, such as an MP3file, or an uncompressed sound file, such as a sound file of the WAVform. Like in the previous example, a compressed or uncompressed soundfile can be recompressed with a lossy method, such as the MP3 or WMAalgorithm, whereby a higher compression rate or lower sampling frequencythan in the original is used, for example. The number of channels of theoriginal sound signal can also be reduced, from stereo to mono, forexample. Recompression and/or reducing the image resolution can also beapplied to video files. For example, video or multimedia clips of theAVI, WMV, MOV, RealMedia, RealVideo or MPG type can be recompressed witha higher compression ratio according to the above described principle.The new quality of the files that are recompressed or processed in otherways may be adjusted according to the capabilities of the mobileterminal used, such as the size of the display or its sound properties.

Methods for the reprocessing of multimedia files like those mentionedabove are well known.

According to an embodiment, the system according to the inventionrecognizes—on the basis of predetermined parameters associated with theform, place or web address—e.g. an image element on a web page as anadvertising image, or a so-called banner. Elements like this are oftenon the top or bottom edge of the image, and their shape is often longerin the horizontal direction than in the vertical direction.

Sometimes they also include animations. An image like this can alsoinclude an external web address, which e.g. points to the advertiser'sown www-pages or some other outside address, or the image itself can bedownloaded from an address outside the web page containing it. Othertypes of advertising images also exist. Methods for recognizing suchadvertising banners are well known in the field.

According to one embodiment, the system according to the inventionchecks that the resource being moved or processed has not already beenmoved as such or moved as processed to the mobile terminal. Wasting thememory capacity of the terminal with duplicated files is thus avoided.

Finally, the downloaded and possibly reprocessed files and pages can bedownloaded to the terminal for later viewing in connection withdownloading e-mail.

According to yet another embodiment, the second terminal itself monitorsthe arriving messages and analyses the references to outside resourcescontained by them.

Because in this case it is not practical for the second terminal totransfer all the information indicated in the external resource to itsown memory, it checks the resource indicated by the reference at first,analyses its content and acts accordingly.

For example, files of a certain type that exceed a certain predeterminedsize are then 30 not transferred to the second terminal. On the otherhand, files of a certain type that fall below a certain predeterminedsize can be transferred, for example image files of a certain type. Inaddition, some files can be compressed when they are transferred,whereby they may fit in the memory of the second terminal. Likewise,resources located in certain addresses or otherwise referring to them,as well as recognized advertising banners can be left untransferred.

FIG. 2 is a flow chart showing some steps of an embodiment of the methodaccording to the invention. At first it is checked whether the messagecontains references to resources outside the message. If it containsthem, it is checked whether the referenced outside resource is a webpage. If it is, it is checked whether the address of that web page is onthe list of allowed addresses. If it is, the structure of the page canbe analysed and it can be checked if there are images on the page, forexample. If there are images, and preferably if they exceed thespecified size limit, they are recompressed. Finally, the page with itsimages is transferred to the mobile terminal. The same procedure isfollowed if the external resource comprises a multimedia file, such asan image, sound or video file. Then the file can be recompressed toreduce its size. The file can also be ignored, if its size exceeds theset limit values or it is other than a multimedia file.

FIG. 3 shows, by way of example, a situation in which a method accordingto the invention is used to analyse and process a web page fortransferring it to a mobile terminal. In the upper part of the figurethere is a web page 30, which includes various elements, such asadvertising banners 32, 34 and 36, text 38 and 40, and a large image 42.Because the purpose is to transfer the web page into a Palm-type PDAdevice with a display of 320×320 pixels, the web page must be modifiedto make it fit on a small display better. This is done in the followingway, for example: The system according to the invention recognizes theadvertising banners 32, 34 and 36 in the upper part of the web page, andremoves them and the hyperlinks connected to them. FIG. 42, which is animage of the jpeg type, sized 140 kilobytes, is reprocessed, whereby thenumber of its colours are reduced from 16 million to 256 colours, itssize is reduced from 500×500 pixels to 150×150 pixels, and finally it iscompressed by using a large, 50 per cent jpeg compression rate, wherebya file of ca. 5 kilobytes 50 is obtained. The text elements 48 and 40are transferred as such. The processed web page 44 obtained as the endresult contains the text elements 46 and 48 and a reprocessed image 50.

Some solutions according to the invention for transferring a message toa mobile terminal have been described above.

The invention is not limited to the solutions described above. Forexample, some file types not mentioned above can be reprocessed inaccordance with the principles discussed above for obtaining a similarresult.
